摘　　要：利用 ECMWF/WMO 客观分析格点资料,分析了多梅年和空梅年大气非绝热加热场特征。结果表明,梅雨期降水与大气非绝热加热场有密切联系,梅雨各阶段的加热场具有不同的特征,丰梅年与空梅年的加热场有显著差异。In the context of ECMWF/WMO objectively analyzed gridded data,study is conduct- ed of the features of atmospheric nonadiabatic heating fields in the years of plentiful and deficient Meiyu rainfall.Evidence suggests that such events bore an intimate relation to these fields;such fields showed different characteristics for different phase of the Meiyu;the fields were distin- guished from each other as regards the features in the years of abundant and less Meiyu precipita- tion.
